MAXHYMAN, OF RELEE, VIRGINIA.

WELL-DIGGING OR EARTH-BORING APPARATUS.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed July 11, 1913. Serial lflo. 778,423.

To all whom it may concern Be it known that 1, MAX HYMAN, a subject of the Czar of Russia, residing at Relee, in the county of Alexandria and State of Virginia, have invented certain new and useful Improvements in Well-Digging or Earth-Boring Apparatus, of which the following is a specification.

This invention relates to a well digging or earth boring apparatus and has for its object, the provision of an improved device of this character adapted to dig wells, post holes, or to make other comparatively deep excavations in the earth.

Further objects and advantages of the invention will be set forth in the detailed description which now follows:

In the accompanying drawings, Figure 1 is a side elevation of a device constructed in accordance with the invention, Fig. 2 is a horizontal sectional view upon line X-X of Fig. 1, Fig. 3 is a detail perspective view of handle securing elements hereinafter described, Fig. 4 is a horizontal section upon line YY of Fig. 1, Fig. 5 is a horizontal section illustrating the central rotative support hereinafter described, Fig. 6 is an under-side face view of a cutter blade hereinafter described, Fig. 7 is a detail perspective view of a portion of the device, Fig. 8 is a sectional view through a pair of interlocking frames hereinafter described. Fig. 9 is a detail perspective view illustrating a curb supporting structure hereinafter described, and Fig. 10 is a detail sectional view through a driving gear hereinafter described.

Like numerals designate corresponding parts in all of the figures of the drawings.

In carrying out the invention, I provide a central standard 5 preferably of Wood and made up of a plurality of sections connected together by bolts 6 and plates 7. As many of these sections may be placed together end to end as the depth of the well or hole may re- Each section carries upon one of its guide 8. A rack bar made up of a plurality of sections 9 is secured to a bar 10 by screws or bolts indicated at 11. The bar 10 is preferably formed of oak faces, a dovetailed though any material may be employed.

The guide 8 is supported from the tapered lower end of the standard 5 by a bracket 12 and said guide 8 in turn supports a fixed rectangular frame 13. The rack bar 9 carries at its lower end a movable rectangular frame 14 made up of the outer section 15 and the inner section 16, these sections being held by bolts or like fastening devices 17. These two frames clamp between them, the edges of a bag 18. The fixed frame 13 receives screws or like fastening devices 19 which passthrongh slots 20 formed in a cutting blade 21. When the rack bar and the movable frame 14 move downwardly, as hereinafter set forth, said frames have dovetailed interlocking engagement with each other as indicated at 22 in Fig. 7, so that when these frames aline with each other, they have interlocking engagement with each other.

The lower end of the standard is provided with an auger 23.

A supporting frame 24 is preferably arranged over the upper end of the excavation 25 when the mechanism is of such weight that it may not be readily handled by hand. When it is desired to operate the device by power, a bevel gear wheel 26 having an an gular opening 27 for the reception of the standard 5, is disposed in such manner as to be held against vertical movement by portions 24 of the frame 24. A shaft 27 is disposed to slide in bearings 28 and may carry either a pulley 29 or other equivalent operating member such for instance as a crank. It is apparent that if rotation be imparted to shaft 27, pinion 30, which has then been moved into engagement with gear wheel 26, will cause rotation of said gear wheel and the standard 5. This will cause the auger 23 to bore into the earth and form a central excavation. At the same time, cutting blade 21 will excavate the earth in its annular path, the dirt thus excavated being forced back into the bag 18, said bag dragging along the bottom of the excavation behind the frame 14.

After the bag has been filled, shaft 27 is moved longitudinally to bring the pinion 30 out of engagement with gear wheel 26 and a second shaft 31 which is slidably disposed in brackets 32, is shifted longitudinally to bring a spur pinion 33 into engagement with the teeth of the rack bar 9.

By imparting rotation to shaft 31 through the medium of the crank 34, it is apparent that longitudinal movement may be imparted to the rack bar to cause this rack bar to travel upwardly and to thereby bring the movable frame 14, together with the filled bag, to the surface where the bag may be emptied or another bag may be substituted therefor, and the movable frame again lowered into engagement with the fixed frame.

If it be desired to rotate the standard by hand rather than by power, handles 35 may be engaged with the standard by employing the U-shaped loops 36 shown in Fig. 3. These loops pass around three sides of the standard and are engaged with the handles as shown.

While I have shown thedevice as of considerable size and arranged to excavate as for a well, it is apparent that the device shown in Fig. 7 may be employed without the power operating means but upon the contrary, be operated entirely by hand for the purpose of digging holes for telephone poles or the like.

If desired, I may employ in conjunction with the structure shown in Fig. 1, a curb supporting device made up of a plurality of annular members 87 which supports the curb here shown as of bricks, indicated at 38. WVhen this device is employed, the annular curb supporting element 87 is placed in position whenthe machine first starts to excavate and the bricks comprising the curb are piled upon the curb supporting device 37 and by their weight, this curb supporting device is forced downwardly and follows the excavating tool closely, settling with the tool. As many bricks may be employed as are required to make a curb of the desired height,

From the foregoing description, it will be seen that simple and eiiicient means are herein provided for accomplishing the obj ects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is:
